CATS Flights

Privacy Policy

Last updated: August 3, 2026

Opening and analyzing a local .cfl file happens in your browser. The file is not sent to CATS unless you explicitly choose Save flight or create an unlisted share.

Information we process

When you create an account, we store the name, email address, profile image, and verification information supplied through Google or email-link sign-in. We also store the profile information and unit preference you choose, essential session records, saved flight metadata and original logs, processed photos, video links, sharing records, and account or content changes needed to operate the service.

Accounts and profiles

Your email address is not displayed on your public profile. Google authentication requests basic identity, email, and profile-image access. When a new account is created, CATS Flights emails info@catsystems.io a notification containing the account name, email address, and signup time. Returning sign-ins do not generate this notification.

Saved and shared flights

Saved flights are private by default. Publishing makes the flight metadata, photos, profile attribution, and downloadable original log public. Unlisted links can be opened and downloaded by anyone who possesses the complete link. Their selected duration is 1, 3, 7, 30, or 90 days. Guest flight data is deleted when its link expires; expiring links for account-owned flights do not delete the underlying saved flight.

Uploaded photos are converted in your browser to WebP, reduced to a maximum dimension and size, and stripped of source metadata such as EXIF before upload. Original source photos are not retained.

Flight pages may include YouTube videos. When a YouTube video approaches the visible part of the page, your browser connects directly to YouTube to load it. YouTube receives normal connection information such as your IP address and browser details, may receive referrer information according to your browser settings, and may use cookies under its own privacy policy. Other media remains an external link and is not loaded by CATS Flights.

Anonymous traffic measurement

We count successful views of public pages using daily aggregates. These aggregates contain only the page category, country code supplied by Cloudflare, device category, and either Direct, Internal, or an external referrer hostname. We do not use an analytics cookie or store IP addresses, user identifiers, full referrer URLs, query strings, or complete user-agent strings, and we do not claim to measure unique visitors or sessions. Private, account, administrator, and unlisted-share pages are excluded.

Cookies and browser storage

We use essential authentication cookies for signed-in sessions. Browser storage is used for device preferences, resuming an explicitly requested save, and retaining the management secret for a guest share created on that device. We do not use advertising cookies.

Service providers and access

Cloudflare hosts application data, file storage, security checks, and site delivery; Cloudflare Turnstile is used for anti-bot protection. Google processes Google sign-in and supplies the privacy-enhanced YouTube player for supported flight media. Namecheap Private Email delivers sign-in links and new-account notifications through CATS mailboxes.

OpenFreeMap supplies map tiles. Nominatim receives a rounded launch coordinate for place-name lookup. For supported saved flights, Open-Meteo receives the launch coordinate and flight hour so CATS Flights can retrieve historical model weather. Open-Meteo does not receive the flight log, account identity, rocket name, or flight title.

Authorized CATS administrators may open or download private flight files to operate or support the service. Administrative private-file access, edits, and deletions are audited.

Retention and deletion

Abandoned staged uploads expire after 24 hours. Guest shares and their uploaded flight data expire after the selected 1, 3, 7, 30, or 90 days. Anonymous daily traffic aggregates are retained indefinitely because they contain no visitor identifiers. You can delete individual flights or your entire account; account deletion removes your profile, sessions, saved flights, photos, and share links.
